"""""Exploring the Universe: Orbiting Objects"""" is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well. The activity models gravitational attraction in space. Participants investigate how changing conditions can cause...

"""""Exploring Earth: Investigating Clouds"""" is a hands-on activity in which visitors create a cloud in a bottle and explore it with laser light. The activity is connected to current and ongoing NASA mission research. Participants learn about ways that NASA uses satellite technology to observe...

"""""Exploring Earth: Rising Sea"""" is a hands-on activity demonstrating ways to use topographical mapping techniques to track changes in sea level. The activity is connected to current NASA research. Together, participants and facilitators can discuss the effects of rising sea levels on coastal...

"""""Exploring the Solar System: Pocket Solar System"""" is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system. They learn that there is a lot of space between planets, and that our solar neighborhood contains many other interesting features...

"""""Exploring Earth: Paper Mountains"""" lets participants explore the way the shape of the land and the pull of gravity influence how water moves over the Earth. By making unique mountain models from crumpled paper and watching how water moves across them, participants can act as Earth scientists,...

"""""Exploring the Solar System: Solar Eclipse"""" is a hands-on activity demonstrating how the particular alignment of the Sun, Earth, and Moon can cause an eclipse. Visitors investigate the positions of these objects to create shadows and learn about solar eclipses."

"""""Exploring the Universe: Ice orbs"""" is a hands-on activity in which visitors investigate a frozen sphere, trying to learn about objects hidden inside. Participants learn that planetary scientists at NASA are investigating """"icy worlds"""" in the outer solar system, looking for evidence of...

"In """"Exploring the Universe: Exoplanet Transits,"""" participants simulate one of the methods scientists use to discover planets orbiting distant stars. Even when a planet is too far away to observe directly, scientists can infer its presence by watching for slight, regular dips in a star's...

"""""Exploring the Solar System: Craters"""" is an active, hands-on activity that demonstrates how craters form, and what they can teach us about the history and composition of planets and moons. By dropping objects of various sizes and shapes into a tub full of sand and other materials,...

"""""Exploring the Universe: Filtered Light"""" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe. Most objects in the universe are so distant from us that we can only study them through the light. Filters allow us...

"""""Exploring the Solar System: Big Sun, Small Moon"""" is a hands-on activity that explores the concept of apparent size and allows visitors to experience this phenomenon using familiar objects -- a tennis ball and a beach ball. Participants learn that the Sun and Moon appear the same size in our...

"In """"Exploring the Solar System: Stomp Rockets,"""" participants learn about how some rockets carry science tools -- not scientists -- into space, and how a special kind of rocket called """"sounding rockets"""" can be used for quick, low-flying missions into space. Participants will build and...
